Return Value

Type: Microsoft.VisualStudio.Modeling.ModelElement
The target element.


A merge operation is what happens when the user uses a tool to create a model element, or performs the paste command, or drags an element onto another. Merge combines the new or copied elements into the existing model.

This method is called when a merge is about to happen. It allows the target element to redirect the merge operation so that another element is the target. For example, a part of a larger object could redirect the merge operation to its parent. This is a benefit for the user, who does not have to distinguish between the part and its parent when dragging a tool or object.

The default method returns this element as the target.
